Disable Game Center in OS X “El Capitan”

OS X Game Center

OS X Game Center

I don’t play games on my Mac. I have never played games on my Mac. I don’t want to play games on my Mac. But Little Snitch tells me that Game Center is constantly phoning home and is clearly doing stuff.

Here’s how to shut it down:

  1. Open Terminal (you’ll find it in Finder > Applications > Utilities);
  2. Type: launchctl unload -w /System/Library/LaunchAgents/com.apple.gamed.plist;
  3. Press enter;
  4. VoilĂ ! Game Center no longer runs.
  5. Quit Terminal.
